This DFG-funded research project has been based on two hypotheses: (I.) The history of sound can be reconstructed as the history of media- and culture-specific concepts of sound. (II.) Specific sound concepts are connected with distinctive conceptions of modernity. Prof. Dr. Jens Gerrit Papenburg, Steffen Just and Carla Jürgens formed the team behind this project. During a conference in Leipzig, Sep 2024, they presented some of their project outcomes. A website has many details incl. audible sound files of digitized rolls. Many people of the GPRM community supported this project, including Peter Philipps and Marc Widuch. In the Department of Musicology and Sound Studies at the Rheinische Friedrich-Wilhelms-Universität Bonn, key questions have been addressed, such as: How can modernity be conceptualized through sound? How can we eavesdrop on the global history of the last 250 years by focusing on sound, specific cultural interdependencies and conflicts, meanings and social structures, technologies and forms of knowledge, the constitution of subjects and bodies, which have been drowned out in previous confrontations with modernity? Part of the output is an amazing tool called Microtime Machine It can be used to analyze time structures on non-quantized standard MIDI files as well as for artistic and creative purposes (e.g., to extract and create microtime patterns from any desired MIDI file) within Ableton Live. The tool is available for free.
